Teck to update QB2 schedule, cost estimates

Diversified mining company Teck Resources is continuing to target first production at the Quebrada Blanca Phase 2 (QB2) copper project, in Chile, by late next year, but the miner warned on Friday that there had been delays in the schedule, primarily owing to permitting and social unrest.

The schedule delays will also affect costs, the Canadian major said of the $4.8-billion copper development project in which it owns 60%, with Sumitomo holding 30% and Chilean State miner Enami the balance.
